Abstract
Magnetoresistive element including a reference layer having a fixed reference magnetization, a sense layer having a free sense magnetization and a tunnel barrier layer between the reference layer and the sense layer; the magnetoresistive element being configured to measure an external magnetic field oriented substantially perpendicular to the plane of the layers. The reference magnetization being oriented substantially perpendicular to the plane of the reference layer. The sense magnetization including a vortex configuration in the absence of an external magnetic field, the vortex configuration being substantially parallel to the plane of the sense layer and having a vortex core magnetization along an out-of-plane axis substantially perpendicular to the plane of the sense layer.
